  • Applications

    (1-Methylcyclopropyl)methanol (CAS 2746-14-7) is used as a synthetic building block in organic synthesis, serving as an intermediate for pharmaceutical active ingredients (APIs) and agrochemical compounds. It is also employed as a precursor in fragrance chemistry for the development of odorant components and related specialty chemicals. As a small alcohol, it can function as a building block for functionalized derivatives used in coatings, inks, and polymer additive formulations. Additionally, it may be used as a solvent or co-solvent in niche formulation contexts, depending on local regulations and formulation limits.
